Custom Cabling and
Optional Connectors
This appendix describes the cabling and connector options.
Custom Cabling
NI offers cables and accessories for use in prototyping your application or
for use if you frequently change device interconnections.
If you want to develop your own cable, however, use the following
guidelines:
•
For the AI signals, use shielded twisted-pair wires for each AI pair,
assuming that you use differential inputs. Connect the shield for each
signal pair to the ground reference at the source.
•
Route the analog lines separately from the digital lines.
•
When using a cable shield, use separate shields for the analog and
digital halves of the cable. Failure to do so results in noise coupling
into the analog signals from transient digital signals.
Mating connectors and a backshell kit for making custom 68-pin cables
are available from NI. The following list gives recommended part numbers
for other connectors that mate to the I/O connector on the NI 6052E:
•
Honda 68-position, solder cup, female connector
•
Honda backshell
